Abstract
For a trailer coupling, the fixing unit has a stationary first toothed segment which is fixedly connected to the pivot bearing base. A first toothed segment which in the working position is connected to the pivot element in a rotationally fixed manner and pivots together with same and is engageable by displacing the pivot element from the pivot position into the fixed position, and is disengageable by displacing the pivot element from the fixed position into the pivot position.

Trailer coupling comprising a mounting unit which is fixedly connectable to a vehicle body;
- a pivot bearing unit, provided on the mounting unit, having a pivot bearing base which is fixedly connected to the mounting unit, and having a pivot element which is pivotable about a pivot axis, relative to the pivot bearing base, between a working position and a rest position, and is displaceable in the direction of the pivot axis between a fixed position and a pivot position;
- a ball neck which at one end is mounted on the pivot element and which at the other end carries a coupling ball, and which, due to the pivotability of the pivot element, is pivotable about the pivot axis between the working position and the rest position, and due to the displaceability of the pivot element is displaceable between the fixed position and the pivot position;
- a fixing unit which, in the fixed position of the pivot element, fixes the pivot element, and thus also the ball neck, relative to the pivot bearing base in a rotationally fixed manner by means of positive-fit elements, and in the pivot position allows pivoting;
- and
- a locking unit, which acts axially against a displacement in the direction of the pivot axis, by means of which, in the fixed position, the fixing unit is fixable against a movement in the direction of the pivot position, the fixing unit having a stationary first toothed segment which is fixedly connected to the pivot bearing base, by means of which a first toothed segment which in the working position is connected to the pivot element in a rotationally fixed manner and pivots together with same, is engageable by displacing the pivot element from the pivot position into the fixed position, and is disengageable by displacing the pivot element from the fixed position into the pivot position.

- a fixing unit which, in the fixed position of the pivot element, fixes the pivot element, and thus also the ball neck, relative to the pivot bearing base in a rotationally fixed manner by means of positive-fit elements, and in the pivot position allows pivoting;
- and
- a locking unit, which acts axially against a displacement in the direction of the pivot axis, by means of which, in the fixed position, the fixing unit is fixable against a movement in the direction of the pivot position, the axially acting locking unit having a central receptacle carrier, which has at least one locking receptacle that is radially outward relative to the pivot axis, the central receptacle carrier being connected to the pivot element to be non-displaceable in the direction of the pivot axis and being movable together with the pivot element in the direction of the pivot axis, the locking unit having at least one locking element, which is situated in a space around the receptacle carrier and may be brought into a locked position that acts on the locking receptacle for holding same in the fixed position, the locking unit having a guide member which is connected to the pivot bearing base and which has at least one guide for the at least one locking element, the guide specifying a direction of movement for the at least one locking element for a movement between the locked position and a released position, the locking unit having an actuating element which acts on the at least one locking element (194) from a side opposite from the receptacle carrier, and by means of the actuating element, a movement of the locking element from the released position into the locked position may be produced, or a movement of the locking element from the locked position into the released position may be enabled.
